Home additions in Long Grove, IL

Expanding a home in Long Grove often means thoughtfully integrating new space into custom-built residences from the 1970s through the 2000s. Many of these homes, while spacious, feature layouts that may no longer suit contemporary lifestyles, making additions a popular choice for achieving desired functionality. Whether it's adding a sunroom that blends seamlessly with the existing architecture or extending a family room to create an open-concept living area, these projects aim to enhance the original character without compromising the rural aesthetic. We frequently work with homes on expansive, wooded lots, where additions can capitalize on natural light and views, transforming the living experience in a way that respects Long Grove's unique development history. The goal is always to create cohesive spaces that feel like they were always part of the home, addressing the evolving needs of families in this distinctive community.

What Long Grove homeowners ask for

Long Grove homeowners frequently request primary suite expansions, creating more luxurious and private retreats within their existing custom homes. Another common request involves adding four-season rooms or conservatories to bring the beauty of their expansive, wooded lots indoors year-round. We also see interest in expanding existing living areas, such as family rooms or dining rooms, to accommodate larger gatherings or to create a more open flow for daily life.

About Long Grove

Long Grove has spent seventy years deliberately not looking like a standard suburb, a character deeply ingrained in its homes and remodeling needs. This means its diverse housing stock offers unique opportunities and considerations for any remodeling project.

How your Long Grove project runs

Process

The same six stages on every job — free in-home estimate through warranty.

1

Free in-home estimate

Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.

2

Itemized scope & contract

Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.

3

Design & selections

Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.

4

Permits & scheduling

We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.

5

The build, owner-supervised

Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.

6

Walkthrough & warranty

We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.

I don't even know where to begin, Patryk & Greg are just amazing! We hired them to remodel approximately 4000 sqft of a 1985 house which included an unfinished basement. The whole experience could not have been better. It took about 7 months and for most of it, we lived in the house with two children. They are incredibly professional, can troubleshoot any issue and are 100% dependable. Patryk led the project and he was very detail-oriented. Everything had a purpose and was finished with beautiful extra touches. I changed my mind frequently and they didn't miss a beat. They worked around the changes and kept moving. The materials they used and the teams they brought in were all top notch. They didn't spend money where it wasn't necessary and in fact, they were always trying to find ways to save money. Finally, they are really nice guys. Polite, respectful and very accomodating. After spending so long in my house, we (almost) miss having the around. As I mentioned, we had the whole house remodeled and its impossible to post every picture so I will showcase just a few highlights. The whole house is beautiful! Scott & I THANK YOU!!!
